The right eastbound lane of the Bowker Overpass connecting Boylston Street and Storrow Drive in Fenway is closed while a Department of Transportation crew repairs a hole detected on the bridge’s deck, said Sara Lavoie, MassDOT spokeswoman.

Lavoie said MassDOT began work early this afternoon and will continue repair of the structure until 4 p.m.

She said there will also be a left lane closure eastbound on Memorial Drive near the Longfellow Bridge later in the afternoon until 8 p.m., as a crew repairs a hole in structure.
